[quote=schist;1223616]A11 is an 11 degree beater angle. Same principle, but apparently the 21 degree angle doesn't work with the shortboards due to the higher footboard angle. So it's been decreased by 10 degrees with this pedal :)[/QUOTE
Are you sure the 21 does not work with the shortboards? Does it really crank up the footboard angle? If so that would not work for me as I'm into low foot boards.
